    Carbon Composition Resistor or Inductor?

    Thanks Delta. Yes. you are correct. The CDM is part of a three piece system used on 88-94 Chevy trucks. This particular CDM is Model #16169561. The part of the circuit I am now most interested in is whatever it is that provides the voltage to the IC (I don't know which IC it is) that is...

    Carbon Composition Resistor or Inductor?

    Thanks for your reply, Bluejets. My reason for thinking it is faulty is because after doing my research, I found that a carbon composition resistor apparently has a history of failure, and if I test it as a resistor, it it obviously not giving me the correct value. As an inductor, it is, at...

    Carbon Composition Resistor or Inductor?

    Hi all. This part has me confused. The color code (Brown, Black, Red, Silver) for it to be a resistor, would make it a 1K Ohm value with a 10% tolerance. Testing it with a multimeter set on Ohms, it comes out to 8.3 ohms, which would obviously be quite low for the value, if it is a resistor...

    Note, John, that you were asking very similar questions in January. What changed? https://maker.pro/forums/threads/knowledge-threshold-from-hobbyist-to-professional.300103/ And then this one also sounds oddly similar...

    Change My Motherboard Myself? Need Recommendations

    Well done, David. No better feeling than eventually seeing the operating system logo appear after a successful boot up. Thanks for returning and telling us about your success.

    Guys, there was a thread from not too long ago that was very similar in nature to this one, in the type of questions asked. I have a feeling the site is being trolled.

    Help identifying USB connector for Dell docking station

    Have you tried to remove the original from the PCB yet? If not, I can understand why not, since I am guessing the one port is still functional.

    Help identifying USB connector for Dell docking station

    I think I am seeing the problem now, after requesting and seeing the bottom of the board. Both USB ports are attached to the PCB with separate through hole pins. I am guessing this has been done to allow for a lot more data transfer through each port. The entire socket connection on the...

    Help identifying USB connector for Dell docking station

    That is a simple two port female USB connector. Most female connectors have that "lip" you are talking about to aid in the insertion of the male USB plug. Are you having a problem fitting a new connector in the space provided, or will the lip interfere with that? The item Bertus suggested is...

    Help identifying USB connector for Dell docking station

    They are both female. Something has happened to the top port and the blue plastic is gone. Likely as Bertus mentioned. It has melted or broken away.

    Tachometer from 1984 Nissan 720

    I am assuming that (AN603) is the correct IC for that board, since it is on that board now, so the provided linked one should work in its place. The schematic Delta Prime suggested would probably help you find out if that is the case, and may even give you the diode specs. If that was mine, I...

    Tachometer from 1984 Nissan 720

    That "resistor" you are talking about is likely a zener diode. I see ZD2 just to the right of it on the board. The sharpie markings appear to be the circuit traces to reference which solder points are connected to each other. But you are right. Someone has likely been in there before and did...

    Need Advice for a USB circuit board

    If you look at the soldered side of his PCB, you can see where the four pins come through it. The ones you are suggesting are smd, as the tabs are parallel with the insertion point. The ones I am suggesting have pins perpendicular to the body of the USB, to fit through those holes. As far as...

    GE Washer Motor Control Board 5KMC145YTA008S Diode Rectifier burnt

    I think Bluejets was talking about damage to other components "in the vicinity" on that same control board. It looks to me like one of the legs on that diode appears to have a cold solder joint on it, which may have been a factor in it burning itself up. Is the diode actually burnt? Can't...

    Need Advice for a USB circuit board

    It looks like you have a salvageable circuit board. You just need to remove the existing solder and replace the USB Fitting afterward, by soldering it in place and bending the perimeter tabs to secure it. I would do that before trying to find an entire module with another tactile switch. If...

    Vizio power board issues

    I have repaired a whole lot of these power supplies from all kinds of manufacturers, just for the fun of it. In most cases, it comes down to bad e-caps. And usually it is the 470uF/10v/16v cap that is bad. If there is one of those on that board, check it first. But I usually just go ahead...
